When applying the script, follow the guide carefully.  This works FAR better on an unmodified V4 than one that's been morphed.  What I've done to avoid exceeding strangeness with joints, is to create a single, weight-mapped and fully Morph ++ injected V4 from which I can re-build all of the V4 characters in my runtime.  I've saved her in a special folder for use in re-building my figures.  Applying the morph dials after conversion yields good results.

Given that I have 9 characters to rebuild, I'm going to be busy for awhile . . .

Thanks again, development team!  She bends beautifully!
